Usher's Marriage on the Rocks?

When your marriage is rocked by breakup rumors on a monthly basis--maybe there's a real problem there.

Both Usher and his wife Tameka Foster have denied a rift in their marriage for months now, but if everything was so peachy keen, why would he move to Las Vegas to work on a new album and leave his wife and kids back in Atlanta?

Tameka is asking the same questions we are, but the difference is, she's pretty upset about it.

"Tameka is really upset that she was asked not to come to Vegas with Usher in December when he left to work on his next album," an industry insider told Page Six.

"She tried to have so much influence over his last project that this time, the people involved with the record said she had to stay away."

His rep insists, "Usher and Tameka have a solid relationship and she understands the demands of his recording schedule. He's been in the studio with Pharrell Williams and Jermaine Dupri working hard on his next album."

We've heard a few horror stories about how possessive Tameka can be. When Usher was filming his music video for "Love In This Club," she reportedly started some drama with the females in the video, which resulted in the studio bosses asking her to leave the set.

On the other hand Tameka just gave birth to the couples second son, Naviyd Ely, on December 12th. She's probably really emotional about being left alone to care for their two kids without him.

We'll have to wait and see how this one unfolds. Do you think they'll make it or are they headed towards splitsville?
